WYP.chat connects Cal.com to your WhatsApp conversations. Every booking, reschedule or cancellation shows in the customer’s conversation and on their record, and the Appointment reminder scenario messages them on WhatsApp the day before, with “I confirm” and “Change”. All it takes is a Cal.com API key, pasted once.
One customer books, another moves their slot, a third cancels: the team sees it in the conversation where they already reply.
At 6 pm the day before, the customer gets a WhatsApp message with two buttons. If they reply “Change”, they get their booking page to pick another slot.
WhatsApp The appointment line says whether it was booked, rescheduled or cancelled. The contact record lists upcoming and past appointments.
WhatsApp When a customer asks for an appointment, the Appointment booking scenario and the AI agent send them your Cal.com page. The confirmation then arrives in the thread.
WhatsApp The integration uses Cal.com’s official API. You paste an API key into WYP.chat, which checks it and subscribes to your bookings itself: no webhook to set up.
The same appointment, booked on your Cal.com page the evening before.
| Step | Without the integration | With Cal.com in WYP.chat |
|---|---|---|
| Know who booked | Open Cal.com or the confirmation email | The appointment in the customer’s conversation |
| Remind the customer | Message each one, or a Cal.com reminder outside your conversations | WhatsApp message the day before, in the conversation where the team replies |
| Move an appointment | Swap messages to find a slot | “Change” sends the Cal.com booking page |
| See the customer’s history | Search in Cal.com | Upcoming and past appointments on the contact record |
At 6 pm the day before, the Appointment reminder scenario sends the customer a WhatsApp message with “I confirm” and “Change”. The day and time are set in the appointment date trigger.
Turn on the appointment reminder, step by step →A few minutes, once for the whole workspace: the key is created in Cal.com and pasted into WYP.chat.
For the workspace owner and admins, on every WYP.chat plan. Only cal.com is supported: a self-hosted Cal.com cannot be connected.
So you know what to expect:
The Cal.com integration is included in every WYP.chat plan, from the Free plan, with unlimited users. On the Free plan, each reminder costs 2 credits (automated message). Your Cal.com subscription stays with Cal.com.
According to Cal.com, its text and WhatsApp reminders are on every Cal.com plan, paid in credits outside the US and Canada. With WYP.chat, the reminder goes from your WhatsApp Business number and lands in the conversation where the team replies: a “Change” reply sends the booking page, and any other question from the customer stays in the same thread.
No. The booking is logged in their conversation, but WYP.chat never writes to them on its own. The only automatic message is the day-before reminder, if the Appointment reminder scenario is active.
No. Only cal.com is supported today.
Not yet. Today WYP.chat sends the link to your Cal.com page, from the Appointment booking scenario or the AI agent, and the booking comes back to the conversation.
No. Only appointments booked, rescheduled or cancelled after the connection reach WYP.chat.
